Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1571626-6 is determined by strict alignment of the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (Momentary)
• Mounting type: Surface Mount
• Actuator orientation: Top Actuated
• Termination style: Gull Wing
• Contact rating voltage: 12VDC or higher
• Contact rating current: 0.05A or higher
• Illumination: Non-Illuminated

Mechanical Compatibility Parameters:

• Outline dimensions must accommodate PCB layout constraints
• Actuator height and switch travel affect mechanical clearance
• Operating force affects user interface consistency

Environmental Compatibility Parameters:

• Operating temperature range must encompass application requirements
• Moisture sensitivity level and RoHS compliance ensure reliability and regulatory conformance

Substitute parts are grouped into two categories based on electrical rating alignment:

Category 1: Exact Electrical Rating Match (0.05A @ 12VDC)

• MJTP1138ATR (APEM Inc.) - Maintains identical contact rating and operating force

Category 2: Enhanced Electrical Rating (0.1A @ 16VDC)

• 7914G-1-000, 7914G-1-000E, 7914G-1-024E, 7914G-1-032E (Bourns Inc.) - All variants provide higher current and voltage ratings with enhanced environmental protection (IP67)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MJTP1138ATR (APEM Inc.)

The MJTP1138ATR is the optimal substitute for direct replacement of the TE Connectivity 1571626-6. This component maintains identical electrical specifications (0.05A @ 12VDC), operating force (160gf), and switch travel (0.25mm). The part is currently in active production status with 50,482 units in stock. ROHS3 compliance and MSL 1 rating ensure regulatory conformance and handling compatibility. The primary design consideration is the increased actuator height (5.00mm versus 2.50mm), which requires verification of mechanical clearance in the target application. The outline dimensions (6.00mm x 6.00mm) are comparable to the original part.

Secondary Substitutes: Bourns 7914G Series (7914G-1-000, 7914G-1-000E, 7914G-1-024E, 7914G-1-032E)

The Bourns 7914G series variants provide enhanced electrical ratings (0.1A @ 16VAC/DC) and IP67 ingress protection, suitable for applications requiring environmental sealing. All variants maintain SPST-NO circuit configuration, top actuation, and gull wing termination. Selection among the four variants depends on packaging requirements and actuator height specifications:

• 7914G-1-000 (Tube packaging): Standard actuator height 4.19mm
• 7914G-1-000E (Cut Tape & Digi-Reel): Standard actuator height 4.19mm
• 7914G-1-024E (Tape & Reel): Flush actuator type, height 2.62mm
• 7914G-1-032E (Cut Tape & Digi-Reel): Standard actuator height 3.43mm

All Bourns variants feature higher operating force (300gf) and reduced mechanical life rating (100,000 cycles versus 1,000,000 cycles). The reduced outline dimensions (5.00mm x 5.00mm) provide PCB space advantages. Extended operating temperature range (-55°C ~ 125°C) accommodates broader environmental applications.

Compliance and Availability:

All substitute parts maintain RoHS3 compliance and MSL 1 moisture sensitivity rating. The MJTP1138ATR offers the highest inventory availability (50,482 units). Bourns variants provide active production status with substantial stock levels (858 to 1,708 units per variant).

Frequently Asked Questions (FAQ)

Q: Can the MJTP1138ATR directly replace the TE Connectivity 1571626-6 without circuit modifications?

A: The MJTP1138ATR maintains identical electrical specifications (0.05A @ 12VDC), circuit configuration (SPST-NO), and switch function (Off-Mom). No circuit modifications are required. However, the increased actuator height (5.00mm versus 2.50mm) requires verification of mechanical clearance above the PCB to prevent interference with enclosure components or adjacent circuitry.

Q: What are the key differences between the MJTP1138ATR and the Bourns 7914G series?

A: The MJTP1138ATR matches the original part's electrical rating (0.05A @ 12VDC) and operating force (160gf), while the Bourns 7914G series provides enhanced electrical ratings (0.1A @ 16VAC/DC) and IP67 environmental protection. The Bourns variants feature higher operating force (300gf) and reduced mechanical life (100,000 cycles versus 1,000,000 cycles). Outline dimensions differ: MJTP1138ATR is 6.00mm x 6.00mm; Bourns variants are 5.00mm x 5.00mm.

Q: Which Bourns 7914G variant should be selected for space-constrained applications?

A: The 7914G-1-024E variant features a flush actuator type with the lowest actuator height (2.62mm), matching the original part's mechanical profile more closely than other Bourns variants. This variant is available in Tape & Reel packaging and maintains all electrical and environmental specifications of the 7914G series.

Q: Are there packaging format differences among the substitute parts?

A: Yes. The MJTP1138ATR is supplied in Tape & Reel (TR) format. Bourns variants are available in multiple packaging formats: 7914G-1-000 (Tube), 7914G-1-000E (Cut Tape & Digi-Reel), 7914G-1-024E (Tape & Reel), and 7914G-1-032E (Cut Tape & Digi-Reel). Packaging selection depends on assembly process requirements and volume specifications.

Q: What is the impact of the higher operating force in the Bourns 7914G series?

A: The Bourns variants require 300gf operating force compared to 160gf for the original part and MJTP1138ATR. This increased force affects user interface feel and may require design consideration in applications where tactile feedback consistency is critical. The higher force provides enhanced durability in high-vibration environments.

Q: How do the operating temperature ranges compare?

A: The original TE Connectivity part operates from -35°C to 85°C. The MJTP1138ATR operates from -20°C to 70°C, providing a narrower range. The Bourns 7914G series operates from -55°C to 125°C, providing extended temperature coverage suitable for industrial and automotive applications. Application temperature requirements determine which substitute is appropriate.

Q: What is the significance of the reduced mechanical life rating in the Bourns variants?

A: The original part and MJTP1138ATR are rated for 1,000,000 cycles, while Bourns variants are rated for 100,000 cycles. This tenfold reduction in mechanical life affects component selection for high-cycle applications. For applications with cycle counts below 100,000, this difference is not operationally significant. For higher-cycle applications, the MJTP1138ATR is the preferred substitute.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original TE Connectivity part is RoHS Compliant. All substitute parts (MJTP1138ATR and all Bourns 7914G variants) are ROHS3 Compliant, meeting current regulatory requirements. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the advantage of IP67 rating in the Bourns variants?

A: IP67 rating indicates dust-tight and waterproof protection, suitable for applications exposed to moisture, dust, or washdown environments. The original TE Connectivity part and MJTP1138ATR do not specify ingress protection. Selection of Bourns variants is appropriate for sealed enclosures or outdoor applications requiring environmental protection.
