Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7301SD9V4ME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (3PDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC / 28V DC)
• Mounting type (Through Hole)
• Actuator specifications (Standard Round, 12.45mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 cycles)
• Base product family (7301SD series)

The C&K 7301SD9V4SE meets all these criteria and qualifies as a direct substitute. Differences in product status and compliance certifications do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 7301SD9V4SE is the direct substitute for the obsolete 7301SD9V4ME. Both components are electrically and mechanically identical across all functional parameters. The primary distinction is product status: the 7301SD9V4SE is active and carries RoHS compliance certification, whereas the 7301SD9V4ME is obsolete and non-compliant.

For new designs or system replacements, the 7301SD9V4SE is the appropriate selection. The active product status ensures ongoing availability and manufacturer support. The RoHS compliance of the substitute aligns with current regulatory requirements for electronic components in most markets.

Frequently Asked Questions (FAQ)

Q: Can the 7301SD9V4SE directly replace the 7301SD9V4ME in existing applications?

A: Yes. The components are electrically and mechanically equivalent. All functional parameters—circuit configuration, current and voltage ratings, mounting type, actuator specifications, and operating temperature range—are identical. Direct substitution is possible without circuit or mechanical redesign.

Q: What is the significance of the RoHS compliance difference?

A: The 7301SD9V4ME is RoHS non-compliant, while the 7301SD9V4SE is RoHS compliant. This affects regulatory compliance for new products and systems subject to RoHS directives. For legacy system maintenance, either part may be acceptable depending on local regulations and customer requirements.

Q: Why is the 7301SD9V4ME listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The 7301SD9V4SE, as an active product within the same 7301SD series, provides continuity of supply and support.

Q: Are there any differences in electrical performance between these parts?

A: No. Both components are rated for 5A at 120V AC / 28V DC with identical electrical life specifications of 100,000 cycles. Performance in circuit applications is equivalent.

Q: What does the REACH Affected status mean for the 7301SD9V4SE?

A: REACH Affected indicates the component is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This is standard for active components and does not affect compatibility or performance.
