Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34ASP13B4V2QT is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-On
• Mounting type must be Through Hole
• Termination style must be PC Pin
• Operating temperature range must encompass -30°C to 85°C
• Actuator type must be Standard Round

Electrical Compatibility Criteria:

• Current rating must support minimum 5A (AC/DC) or be suitable for lower-current applications where design permits
• Voltage ratings must meet or exceed 125V AC and 28V DC, or be acceptable for lower-voltage applications
• RoHS and REACH compliance status must be documented

Mechanical Compatibility Criteria:

• Actuator length variations are acceptable within design constraints
• Bushing thread type (Unthreaded) must match
• Illumination status (Non-Illuminated) must match

The substitute parts listed below satisfy these core criteria while offering variations in manufacturer, packaging, electrical life, and specific voltage/current ratings.

Parameter Comparison

Engineering Selection Recommendations

Full-Specification Equivalents (5A, 125V AC / 28V DC):

The 100AWSP1T1B4VS3QE (E-Switch) and 7101SD9V3GE (C&K) are direct electrical equivalents to the 34ASP13B4V2QT. Both maintain 5A current rating and 120V AC / 28V DC voltage specifications. The E-Switch part is Active in product status with higher inventory (1270 units) and includes IP67 ingress protection with epoxy sealed terminals. The C&K 7101SD9V3GE is also Active with 1123 units available and offers extended electrical life (100,000 cycles versus 40,000). Both parts are ROHS3 compliant.

Lower-Current Alternatives (0.4VA, 20V AC/DC):

The 7101SD9V3BE and 7101SY9V3BE (C&K) are suitable only for applications where current and voltage requirements do not exceed 0.4VA and 20V. These parts offer significantly extended electrical life (100,000 cycles) and are available in higher quantities (3094 and 988 units respectively). Selection of these parts requires confirmation that the application does not require the full 5A / 125V specifications of the primary part.

Obsolete Status Alternatives (6A AC, 125V AC / 30V DC):

The M2012SA2A13 and M2012SA2W13-BC (NKK Switches) are marked as Obsolete in product status. While these parts exceed the current rating (6A AC / 4A DC) and voltage specifications (125V AC / 30V DC), their obsolete status indicates limited future availability. The M2012SA2W13-BC includes a red actuator cap, distinguishing it mechanically from the standard round actuator of the primary part. These parts should be selected only when inventory of Active alternatives is exhausted and design constraints permit the use of obsolete components.

Compliance and Certification:

All substitute parts maintain RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. The primary part is RoHS Compliant; substitute parts are ROHS3 Compliant, representing an updated regulatory standard. REACH status varies: the primary part and NKK parts are REACH Unaffected, while C&K and E-Switch parts are REACH Compliant or REACH Unaffected as documented.

Frequently Asked Questions (FAQ)

Q: Can the 7101SD9V3BE or 7101SY9V3BE be used as direct replacements for the 34ASP13B4V2QT?

A: No. These C&K parts are rated for 0.4VA at 20V AC/DC, which is significantly lower than the primary part's 5A at 125V AC / 28V DC specifications. They are suitable only for low-power applications where the reduced current and voltage ratings are acceptable. Verify application requirements before substitution.

Q: What is the difference between the E-Switch 100AWSP1T1B4VS3QE and the C&K 7101SD9V3GE?

A: Both parts maintain equivalent electrical specifications (5A, 120V AC / 28V DC). The E-Switch part includes IP67 ingress protection and epoxy sealed terminals, making it suitable for environments requiring dust and moisture resistance. The C&K part offers extended electrical life (100,000 cycles versus 30,000 cycles for E-Switch). The E-Switch part is packaged in Bulk format, while the C&K part is supplied in Tray packaging. Selection depends on environmental requirements and packaging preferences.

Q: Why are the NKK M2012SA2A13 and M2012SA2W13-BC marked as Obsolete?

A: Obsolete status indicates that these parts are no longer in active production and have limited future availability. While they exceed the electrical specifications of the primary part (6A AC / 4A DC at 125V AC / 30V DC), their obsolete designation means inventory will eventually be depleted. These parts should be considered only as secondary alternatives when Active parts are unavailable.

Q: What does the "Red Cap" feature on the M2012SA2W13-BC indicate?

A: The M2012SA2W13-BC includes a red actuator cap as a distinguishing mechanical feature. This is a cosmetic and functional identifier that differentiates it from the standard round actuator of the primary part. The cap does not affect electrical performance but may impact panel aesthetics and actuator tactile feedback.

Q: Are all substitute parts suitable for the same operating temperature range?

A: Yes. All substitute parts listed operate across -30°C to 85°C, matching the primary part's operating temperature specification. This parameter is consistent across all alternatives and does not require verification during substitution.

Q: What is the significance of electrical life differences among the substitute parts?

A: Electrical life indicates the number of switching cycles a part can withstand before performance degradation. The primary part is rated for 40,000 cycles. The C&K 7101 series parts offer 100,000 cycles, providing extended service life. The NKK parts offer 25,000 cycles, which is lower than the primary part. Selection should consider the application's expected switching frequency and required component longevity.

Q: Can packaging format affect substitution decisions?

A: Yes. The primary part is supplied in an unspecified format (-). Substitute parts are available in Bulk (E-Switch, NKK) or Tray (C&K) packaging. Bulk packaging typically contains larger quantities suitable for high-volume assembly, while Tray packaging is used for smaller quantities or automated pick-and-place operations. Verify that the substitute part's packaging format is compatible with your procurement and assembly processes.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: RoHS Compliant refers to the original Restriction of Hazardous Substances directive. ROHS3 Compliant refers to the updated RoHS 3 directive (2015/863/EU), which includes additional restricted substances. All substitute parts meet ROHS3 standards, which is more stringent than the primary part's RoHS Compliant status. This represents regulatory alignment and does not negatively impact substitution compatibility.

Q: How do actuator length variations affect mechanical compatibility?

A: The primary part has a 13.97mm actuator length. Substitute parts range from 10.67mm to 12.70mm. Actuator length affects the distance the toggle extends from the panel surface. Shorter actuators may require different panel cutout positioning or user interface design considerations. Verify that the substitute part's actuator length is compatible with your panel layout and user interaction requirements before final selection.
