Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5223055-4 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part 5223002-4 qualifies as a direct equivalent because it maintains identical specifications in the following key areas:

Electrical Parameters: Voltage rating of 30V, operating temperature range of -55°C to 125°C, and gold contact finish remain unchanged.

Mechanical Parameters: 120-position count, 0.079" (2.00mm) pitch, 5-row configuration, through-hole mounting, and press-fit termination are identical.

Physical Characteristics: Connector style (Futurebus), connector type (header with male pins), color (natural), and material flammability rating (UL94 V-0) are preserved.

Compliance & Certification: Both parts maintain RoHS compliance and MSL 1 rating. The substitute part carries ROHS3 Compliant status, representing an updated compliance designation for the same product line.

The primary distinction is product status: the original part is obsolete while the substitute is active, with the substitute available in tube packaging.

Engineering Selection Recommendations

The TE Connectivity 5223002-4 is the direct functional equivalent for the obsolete 5223055-4. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The substitute part carries active product status, ensuring continued availability and manufacturing support. The original part's obsolete classification necessitates transition to an equivalent active part for new designs and ongoing procurement.

Compliance Equivalence: Both parts meet UL94 V-0 flammability requirements and maintain MSL 1 moisture sensitivity ratings. The substitute's ROHS3 Compliant designation represents current regulatory compliance documentation for the same product line, superseding the original RoHS Compliant designation.

Electrical and Mechanical Compatibility: All critical parameters—voltage rating, temperature range, connector configuration, pitch, position count, and termination method—are identical between the main part and substitute. This ensures direct functional interchangeability in PCB designs and backplane applications.

Packaging Consideration: The substitute is supplied in tube packaging, which is standard for production quantities of this connector type and does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 5223002-4 be used as a direct replacement for the 5223055-4 in existing designs?

A: Yes. The 5223002-4 is electrically and mechanically identical to the 5223055-4 across all specified parameters. Both parts feature 120 positions, 0.079" pitch, 5-row configuration, through-hole mounting, press-fit termination, gold contacts, and identical voltage and temperature ratings. No design modifications are required.

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

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 Compliant represents the current regulatory documentation standard for the product line. The substitute part carries this updated designation while maintaining the same material composition and compliance level as the original part.

Q: Are there any packaging differences that affect component handling or installation?

A: The substitute part is supplied in tube packaging, which is standard for this connector category. Tube packaging does not affect the electrical performance, mechanical fit, or installation process. Handling and storage requirements remain consistent with standard backplane connector practices.

Q: Why is the original part classified as obsolete?

A: Product obsolescence typically reflects manufacturer lifecycle decisions. The availability of the functionally equivalent 5223002-4 as an active part ensures that applications requiring this connector type can transition to a supported product without performance compromise.

Q: Are the contact finish specifications identical between both parts?

A: Yes. Both the 5223055-4 and 5223002-4 feature gold-plated contacts with identical finish specifications. Contact finish thickness is not specified in the available data for either part.

Q: Do both parts meet the same temperature and voltage operating ranges?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C and carry a 30V voltage rating. These specifications are unchanged between the main part and substitute.
