Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 34BWSP31B4V2RT are qualified based on strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Off-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Through Hole
• Actuator type: Standard Round
• Termination style: PC Pin
• Operating temperature range: -30°C ~ 85°C
• Actuator material: Brass, Chrome Plated

Allowable Variations:

• Actuator length (within mechanical envelope constraints)
• Ingress protection rating (equal or superior)
• Electrical life cycles (equal or superior)
• Packaging format (Bulk, Tray, or standard)
• Manufacturer identity (different manufacturers acceptable)
• RoHS compliance status (both RoHS2 and RoHS3 acceptable)

The substitute parts 7103MD9V4BE and E103SD1V3BE meet all critical electrical parameters and mounting specifications, enabling functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

34BWSP31B4V2RT (Grayhill Inc.) remains the primary specification when available. This part offers the highest ingress protection rating (IP67) and electrical life rating (50,000 cycles), with RoHS compliance and active product status.

7103MD9V4BE (C&K) serves as a functional substitute when the primary part is unavailable. This part meets all critical electrical and mechanical parameters. The reduced actuator length (6.86 mm versus 12.60 mm) requires mechanical envelope verification for panel cutout compatibility. Ingress protection is not specified; applications requiring IP67 or higher protection should confirm environmental suitability. Electrical life is rated at 40,000 cycles. ROHS3 compliance and active product status are confirmed.

E103SD1V3BE (C&K) provides an alternative substitute with actuator length (12.70 mm) closely matching the original specification. Ingress protection is rated IP57, which is lower than the original IP67 rating; applications in harsh environments should evaluate this reduction. Electrical life is rated at 40,000 cycles. ROHS3 compliance and active product status are confirmed.

Selection between substitute parts depends on mechanical envelope constraints (actuator length) and environmental protection requirements (ingress protection rating). All three parts are active products with confirmed compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can 7103MD9V4BE replace 34BWSP31B4V2RT in all applications?

A: 7103MD9V4BE matches all critical electrical parameters (SPDT, 0.4VA, 20V AC/DC, On-Off-On function) and mounting specifications (through-hole, PC pin termination). The primary consideration is actuator length: 7103MD9V4BE measures 6.86 mm compared to 12.60 mm for the original. Panel cutout and mechanical envelope compatibility must be verified. Ingress protection is not specified for this part; if IP67 protection is required, this specification gap must be addressed through application review.

Q: What is the difference between E103SD1V3BE and 7103MD9V4BE?

A: Both parts are C&K manufactured SPDT toggle switches with identical electrical ratings (0.4VA, 20V AC/DC). The primary differences are: (1) Actuator length: E103SD1V3BE is 12.70 mm, 7103MD9V4BE is 6.86 mm; (2) Ingress protection: E103SD1V3BE is rated IP57, 7103MD9V4BE is not specified; (3) Packaging: E103SD1V3BE is supplied in Tray format, 7103MD9V4BE in Bulk format; (4) Series designation: E series versus 7000 series. Both have 40,000 cycle electrical life ratings.

Q: Is the reduced electrical life of substitute parts (40,000 cycles versus 50,000 cycles) significant?

A: The 10,000 cycle difference represents a 20% reduction in rated electrical life. For applications with high switching frequency or long operational life requirements, this difference should be evaluated against actual duty cycle expectations. Both ratings exceed typical industrial switch requirements for standard control applications.

Q: Can E103SD1V3BE be used in applications requiring IP67 protection?

A: E103SD1V3BE is rated IP57 (dust protected, waterproof) rather than IP67 (dust tight, waterproof). These are distinct ingress protection levels. Applications requiring IP67 protection should use the original 34BWSP31B4V2RT or conduct environmental testing to confirm IP57 adequacy for the specific application.

Q: Are all three parts RoHS compliant?

A: Yes. The original 34BWSP31B4V2RT is RoHS Compliant. Both substitute parts (7103MD9V4BE and E103SD1V3BE) are ROHS3 Compliant. ROHS3 represents current RoHS directive compliance and is acceptable for new designs and applications.

Q: What packaging formats are available?

A: 34BWSP31B4V2RT is supplied in standard packaging (format not specified). 7103MD9V4BE is supplied in Bulk packaging. E103SD1V3BE is supplied in Tray packaging. Packaging selection may affect minimum order quantities and handling requirements; verify packaging compatibility with procurement and assembly processes.
