Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S5B-ZR-SM3A-TF is determined by the following critical parameters:

Primary Matching Criteria:

• Pitch - Mating: 0.059" (1.50mm)
• Number of Positions: 5
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount, Right Angle
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Detent Lock
• Voltage Rating: 50V minimum
• Current Rating: 1A minimum
• Material Flammability Rating: UL94 V-0

Secondary Compatibility Parameters:

• Operating Temperature range compatibility
• Contact material and finish composition
• Insulation material properties
• Mechanical dimensions (insulation height, contact shape)

Parts meeting all primary criteria are classified as direct equivalents. Parts meeting primary criteria with minor variations in secondary parameters are classified as similar substitutes.

Engineering Selection Recommendations

S5B-ZR-SM4A-TF (Direct Equivalent - Recommended Primary Substitute)

The S5B-ZR-SM4A-TF is the direct equivalent for the obsolete S5B-ZR-SM3A-TF. Both parts share identical electrical and mechanical specifications within the ZH series from JST Sales America Inc. The primary distinction is product status: S5B-ZR-SM4A-TF is active with current manufacturing availability (2626 pcs in stock), whereas the main part is obsolete. The S5B-ZR-SM4A-TF carries ROHS3 compliance, addressing regulatory requirements that the original part does not meet. Contact finish differs from Tin-Lead to Tin, which maintains electrical performance while improving environmental compliance. Insulation material composition differs slightly (PA6T vs PA46), but both meet UL94 V-0 flammability requirements and operate within the same temperature range. This part is suitable for direct replacement in new designs and production continuity.

292228-5 (Similar Substitute - Alternative Option)

The 292228-5 from TE Connectivity AMP Connectors is a similar substitute that meets all primary electrical and mechanical matching criteria. Key differences include: insulation height of 0.193" (4.90mm) versus 0.146" (3.70mm), square contact shape versus circular, and expanded operating temperature range (-30°C ~ 105°C). The part is ROHS3 compliant and carries active product status with 1800 pcs in stock. Current rating is specified as "Varies by Wire Gauge" rather than fixed 1A. This part is suitable for applications where the dimensional and thermal variations are acceptable within the design envelope.

Frequently Asked Questions (FAQ)

Q: Why is the S5B-ZR-SM3A-TF obsolete, and what are my options?

A: The S5B-ZR-SM3A-TF has reached end-of-life status. The S5B-ZR-SM4A-TF is the direct replacement from the same manufacturer and series, offering identical form, fit, and function with improved compliance status. The 292228-5 is an alternative from a different manufacturer that meets the same electrical and mechanical requirements.

Q: Can I use S5B-ZR-SM4A-TF as a direct drop-in replacement?

A: Yes. The S5B-ZR-SM4A-TF is a direct equivalent with identical pitch, position count, mounting type, and electrical ratings. The contact finish change from Tin-Lead to Tin does not affect electrical performance. No design modifications are required.

Q: What are the key differences between S5B-ZR-SM4A-TF and 292228-5?

A: The primary differences are: insulation height (3.70mm vs 4.90mm), contact shape (circular vs square), operating temperature range (-25°C to 85°C vs -30°C to 105°C), and manufacturer (JST vs TE Connectivity). Both meet the same voltage, current, and flammability requirements. Selection depends on PCB layout constraints and thermal operating conditions.

Q: Are there packaging differences between these parts?

A: S5B-ZR-SM4A-TF is available in Cut Tape (CT) and Digi-Reel packaging. The 292228-5 is supplied in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly line requirements.

Q: Do all substitute parts meet RoHS compliance?

A: The original S5B-ZR-SM3A-TF is RoHS non-compliant. Both substitute parts (S5B-ZR-SM4A-TF and 292228-5) are ROHS3 compliant, meeting current environmental regulations.

Q: What is the mating pitch, and is it consistent across all parts?

A: All three parts operate at 0.059" (1.50mm) mating pitch. This is the critical parameter ensuring mechanical and electrical compatibility in mating applications.

Q: Can I mix these connectors in the same assembly?

A: All three parts are compatible with the same mating connectors due to identical pitch and position configuration. However, physical dimensions (insulation height, contact shape) differ between the 292228-5 and the JST parts, which may affect PCB layout and mechanical fit. Verify dimensional compatibility within your specific application.
