Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SDS-51J is determined by the following critical parameters:

• Connector Configuration: Receptacle, female sockets with 5 positions
• Shell Geometry: DIN 240-degree insert specification
• Mounting Architecture: Through-hole, right-angle orientation
• Electrical Interface: Solder termination with push-pull fastening
• Mechanical Compatibility: Keyed orientation for polarization

The substitute part 61PC5F (Switchcraft Inc.) satisfies these core substitution criteria. Both components share identical connector type, position count, shell size, mounting method, termination style, and fastening mechanism. These parameters ensure mechanical and electrical interchangeability at the board level.

Parameter Comparison

Engineering Selection Recommendations

The 61PC5F represents an active-status substitute for the obsolete SDS-51J. Both components maintain identical mechanical and connector specifications, ensuring direct board-level compatibility.

The 61PC5F carries ROHS3 compliance, exceeding the RoHS compliance level of the original SDS-51J, making it suitable for applications requiring current regulatory adherence. Both parts share the same export classification (EAR99) and tariff code (8536.69.4020).

Electrical parameter differences exist: the 61PC5F supports 3A current rating versus the SDS-51J's 2A rating, and operates at 34VDC versus the SDS-51J's 100VAC specification. These differences require circuit-level validation to confirm compatibility with the intended application's electrical requirements.

Frequently Asked Questions (FAQ)

Q: Can the 61PC5F directly replace the SDS-51J in existing assemblies?

A: Mechanical and connector compatibility is confirmed. Electrical parameter validation is required. The 61PC5F's 3A current rating and 34VDC voltage specification must be cross-referenced with circuit requirements before implementation.

Q: What is the primary reason for seeking a substitute for the SDS-51J?

A: The SDS-51J is classified as obsolete. The 61PC5F is an active product, ensuring ongoing availability and supply chain continuity.

Q: Are both parts RoHS compliant?

A: Yes. The SDS-51J is RoHS Compliant. The 61PC5F is ROHS3 Compliant, representing a higher compliance standard.

Q: What packaging is available for the 61PC5F?

A: The 61PC5F is supplied in bulk packaging, with 803 pieces available in new original stock.

Q: Do both connectors use the same termination method?

A: Yes. Both the SDS-51J and 61PC5F employ solder termination with push-pull fastening and through-hole, right-angle mounting.
