Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SCWCQE is determined by strict alignment of the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Mounting type must be Panel Mount
• Panel cutout dimensions must be Circular - 6.35mm Dia
• Bushing thread must be 1/4-40
• Termination style must be PC Pin
• Operating temperature range must encompass -30°C to 85°C
• RoHS3 compliance required

Electrical Rating Considerations: Substitutes are grouped based on electrical performance. The 7201SCWCQE operates at 5A (AC/DC) with 120V AC and 28V DC ratings. Substitute parts with lower current or voltage ratings (0.4VA at 20V) represent reduced-capability alternatives suitable only for applications with lower electrical demands.

Mechanical Compatibility: All substitute candidates maintain identical panel mounting interfaces (6.35mm circular cutout, 1/4-40 bushing thread) and PC pin termination, ensuring direct mechanical interchangeability in panel installations.

Parameter Comparison

Engineering Selection Recommendations

Full Electrical Equivalents: The E-Switch 100DP1T1B1M2QEH provides complete electrical and mechanical equivalence to the 7201SCWCQE. Both parts maintain identical 5A (AC/DC) current ratings and 120V AC / 28V DC voltage specifications. This substitute is suitable for direct replacement in applications requiring the full electrical performance envelope of the original part. Both manufacturers maintain active product status and ROHS3 compliance.

Reduced-Capability Substitutes: The E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 are mechanically compatible but electrically limited to 0.4VA at 20V (AC/DC). These parts maintain identical panel mounting interfaces and termination styles. Selection of these substitutes is restricted to applications with electrical demands not exceeding 0.4VA at 20V. Both parts are active production items with ROHS3 compliance. The TE Connectivity part carries REACH Affected status, matching the original 7201SCWCQE.

Compliance Considerations: All substitute candidates maintain ROHS3 compliance. The original 7201SCWCQE and TE Connectivity 2-1825138-4 are both REACH Affected. The E-Switch alternatives are REACH Unaffected. Regulatory requirements for your application determine whether REACH status is a selection factor.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T1B1M2QEH replace the C&K 7201SCWCQE in all applications? A: Yes, the 100DP1T1B1M2QEH provides complete electrical and mechanical compatibility. Both parts share identical current ratings (5A AC/DC), voltage specifications (120V AC / 28V DC), panel mounting dimensions, and operating temperature ranges. Direct substitution is valid for applications utilizing the full electrical performance of the original part.

Q: What is the difference between the E-Switch 100DP1T1B1M2QEH and 100DP1T6B15M2RE? A: The primary difference is electrical rating. The 100DP1T1B1M2QEH maintains 5A at 120V AC / 28V DC, matching the original part. The 100DP1T6B15M2RE is rated for 0.4VA at 20V AC/DC, representing a reduced-capability variant. Both share identical mechanical interfaces and panel mounting specifications. Selection depends on application electrical requirements.

Q: Can I use the TE Connectivity 2-1825138-4 as a substitute? A: The 2-1825138-4 is mechanically compatible but electrically limited to 0.4VA at 20V. Use this part only in applications where electrical demands do not exceed these ratings. Mechanical interchangeability is confirmed through identical panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and PC pin termination.

Q: Are there packaging differences between these substitutes? A: The original 7201SCWCQE is supplied in Tray packaging. All substitute parts are supplied in Bulk packaging. Packaging format does not affect electrical or mechanical performance and is a procurement consideration only.

Q: Do all substitutes meet the same compliance standards? A: All parts are ROHS3 compliant and active production items. The 7201SCWCQE and TE Connectivity 2-1825138-4 are REACH Affected. The E-Switch alternatives (100DP1T1B1M2QEH and 100DP1T6B15M2RE) are REACH Unaffected. Verify REACH compliance requirements for your specific application and regulatory jurisdiction.

Q: What is the electrical life difference between these parts? A: The C&K 7201SCWCQE is rated for 100,000 electrical cycles. The E-Switch 100DP1T1B1M2QEH is rated for 40,000 cycles. The E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 are rated for 40,000 and 6,000 cycles respectively. Application duty cycle requirements determine whether these differences are significant for your use case.
