TE Connectivity ALCOSWITCH 1825099-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH 1825099-2 is a pushbutton switch with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration, rated for 0.4VA at 20V AC/DC. This component features a round plunger actuator with red cap, through-hole mounting, and PC pin termination. The part is classified as obsolete, making identification of equivalent substitute components necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 1825099-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC minimum

Mechanical Compatibility Requirements:

• Mounting type: Through Hole
• Actuator type: Round, Plunger
• Termination style: PC Pin

Environmental & Reliability Requirements:

• Operating temperature range: Minimum -30°C to 65°C
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 800SP9B6M2RE from E-Switch meets all critical electrical and mechanical parameters. Differences in actuator color (black versus red), mechanical life rating (50,000 versus unlimited), and operating temperature upper limit (85°C versus 65°C) represent enhancements or variations that do not prevent functional substitution.

Engineering Selection Recommendations

Primary Substitute: E-Switch 800SP9B6M2RE

The E-Switch 800SP9B6M2RE is the qualified substitute for the obsolete TE Connectivity ALCOSWITCH 1825099-2. This recommendation is based on:

1. Electrical Equivalence: Identical circuit configuration (SPST-NO), switch function (Off-Mom), current rating (0.4VA AC/DC), and voltage ratings (20V AC/DC).

2. Mechanical Equivalence: Matching mounting type (through hole), actuator type (round plunger), and termination style (PC pin) ensure direct board-level compatibility without redesign.

3. Environmental Compliance: Both components share MSL 1 (Unlimited) moisture sensitivity rating. The E-Switch component extends the operating temperature range to 85°C, providing enhanced thermal margin.

4. Product Status & Support: The E-Switch 800SP9B6M2RE is actively manufactured and supported, addressing the obsolescence of the original TE Connectivity component. The part is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

5. Inventory Availability: E-Switch 800SP9B6M2RE is available in higher stock quantities (2341 pieces) compared to the original part (1104 pieces), supporting production continuity.

Design Consideration: The E-Switch substitute exhibits lower electrical life rating (50,000 cycles versus 100,000 cycles). Applications requiring extended cycle life beyond 50,000 operations should evaluate this parameter against actual duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 800SP9B6M2RE directly replace the TE Connectivity ALCOSWITCH 1825099-2 without PCB modification?

A: Yes. Both components share identical mounting type (through hole), actuator type (round plunger), and termination style (PC pin). Direct board-level substitution is supported without layout or footprint changes.

Q: What is the significance of the different actuator colors (red versus black)?

A: Actuator color is a cosmetic and functional marking feature only. The red cap on the original TE Connectivity component and black cap on the E-Switch substitute do not affect electrical performance or mechanical operation. Color selection should be based on application-specific visual identification requirements.

Q: How does the difference in electrical life (100,000 cycles versus 50,000 cycles) impact component selection?

A: Electrical life rating indicates the number of switching cycles the component is rated to perform before degradation. Applications with duty cycles below 50,000 total operations over the component lifetime are unaffected. Applications approaching or exceeding 50,000 cycles should evaluate actual operational requirements against the E-Switch rating.

Q: Are there compliance or certification differences between the two components?

A: The E-Switch 800SP9B6M2RE is RoHS3 compliant and REACH unaffected, meeting current regulatory standards. Both components share EAR99 ECCN classification and identical HTSUS codes (8536.50.9031). The E-Switch component represents current manufacturing standards.

Q: What is the packaging difference, and does it affect component selection?

A: The TE Connectivity ALCOSWITCH 1825099-2 is supplied with standard packaging, while the E-Switch 800SP9B6M2RE is supplied in bulk packaging. Bulk packaging typically reduces per-unit cost and is suitable for production environments. Packaging format does not affect component performance or compatibility.

Q: Can the E-Switch 800SP9B6M2RE operate at the full 85°C upper temperature limit in all applications?

A: The E-Switch component is rated for -30°C to 85°C operation. The original TE Connectivity component is rated to 65°C. Applications operating between 65°C and 85°C benefit from the extended thermal rating of the E-Switch substitute. Applications below 65°C operate within both component specifications.

Q: Is the E-Switch 800SP9B6M2RE suitable for new design applications, or only for replacement of obsolete components?

A: The E-Switch 800SP9B6M2RE is actively manufactured and supported, making it suitable for both new design applications and replacement of obsolete components. Active product status ensures long-term availability and supply chain continuity.
