S9B-ZR-SM3A-TF Equivalent & Substitute Parts

Part Overview

The S9B-ZR-SM3A-TF is a rectangular connector header manufactured by JST Sales America Inc., designed for surface mount, right-angle applications with 9 positions at 1.5mm pitch. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S9B-ZR-SM3A-TF is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Pitch: 9 positions at 0.059" (1.50mm) mating pitch
• Mounting & Orientation: Surface mount, right-angle configuration
• Electrical Ratings: 1A current and 50V voltage minimum
• Shrouding & Fastening: Shrouded 4-wall design with detent lock
• Termination Method: Solder termination
• Environmental Rating: UL94 V-0 flammability compliance

Two substitute parts meet these core substitution criteria with allowable variations in contact finish, insulation material composition, and product status.

Parameter Comparison

Engineering Selection Recommendations

S9B-ZR-SM4A-TF is the primary direct substitute for the S9B-ZR-SM3A-TF. Both components are from the JST ZH series with identical electrical and mechanical specifications. The S9B-ZR-SM4A-TF is currently in active production status with RoHS compliance, addressing the obsolescence of the main part. Contact finish differs from Tin-Lead to Tin, and insulation material composition varies from PA46 to PA6T, both acceptable within the connector category. This part maintains full compatibility with existing PCB designs and mating connectors.

292228-9 from TE Connectivity AMP Connectors represents a cross-manufacturer alternative. While it maintains the same 9-position, 1.5mm pitch, surface-mount right-angle configuration, it introduces mechanical variations: increased insulation height (0.193" vs. 0.146"), square contact shape (vs. circular), and extended operating temperature range (-30°C ~ 105°C vs. -25°C ~ 85°C). These differences require PCB layout verification and mating connector compatibility assessment. This option provides the highest inventory availability and ROHS3 compliance.

Selection between S9B-ZR-SM4A-TF and 292228-9 depends on design constraints: choose S9B-ZR-SM4A-TF for direct form-fit-function replacement; choose 292228-9 only when PCB layout accommodates the increased insulation height and contact geometry differences.

Frequently Asked Questions (FAQ)

Q: Can S9B-ZR-SM4A-TF be used as a direct replacement for S9B-ZR-SM3A-TF?

A: Yes. Both components share identical pitch (1.50mm), position count (9), mounting type (surface mount right-angle), and electrical ratings (1A, 50V). The contact finish change from Tin-Lead to Tin and insulation material variation from PA46 to PA6T do not affect functional compatibility. The S9B-ZR-SM4A-TF is the recommended substitute due to active product status and RoHS compliance.

Q: What are the key differences between S9B-ZR-SM4A-TF and 292228-9?

A: Both maintain the core 9-position, 1.5mm pitch, surface-mount right-angle header configuration. Differences include: manufacturer (JST vs. TE Connectivity), series designation (ZH vs. Mini CT), insulation height (3.70mm vs. 4.90mm), contact shape (circular vs. square), and operating temperature range (-25°C to 85°C vs. -30°C to 105°C). The 292228-9 requires PCB layout verification due to increased insulation height.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The S9B-ZR-SM3A-TF is RoHS non-compliant. Both S9B-ZR-SM4A-TF (RoHS Compliant) and 292228-9 (ROHS3 Compliant) meet current RoHS requirements. For new designs or procurement requiring RoHS compliance, either substitute is acceptable.

Q: Does the contact shape difference (circular vs. square) affect mating compatibility?

A: Contact shape is a mechanical feature that affects mating connector design. The S9B-ZR-SM4A-TF maintains the circular contact shape of the original part. The 292228-9 uses square contacts, which requires verification that the mating connector socket geometry accommodates this geometry. Cross-manufacturer substitution with contact shape changes requires design review.

Q: What is the impact of insulation height variation on PCB layout?

A: The S9B-ZR-SM4A-TF maintains the original 0.146" (3.70mm) insulation height. The 292228-9 has increased insulation height of 0.193" (4.90mm). This difference affects clearance to adjacent components and may require PCB layout modification. Verify clearance requirements before selecting the 292228-9 as a substitute.

Q: Which substitute part offers the best inventory availability?

A: The 292228-9 from TE Connectivity provides the highest inventory availability at 25,339 pieces. The S9B-ZR-SM4A-TF offers 3,142 pieces. Both are in active production with unlimited moisture sensitivity level (MSL 1).
