Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSM-120-L-DV-TR are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain identical current rating (5.2A per contact), voltage rating (405VAC, 572VDC), and operating temperature range (-55°C ~ 125°C).

Mechanical Compatibility: All substitute parts share the same connector type (Receptacle, Pass Through), number of positions (40), pitch (0.100"/2.54mm), number of rows (2), row spacing (0.100"/2.54mm), and mounting type (Surface Mount).

Contact Specifications: All parts feature identical contact type (Female Socket), contact finish (Gold at 10.0µin/0.25µm), contact material (Phosphor Bronze), and contact shape (Square).

Material and Compliance: All parts use Liquid Crystal Polymer (LCP) insulation, are ROHS3 compliant, and have MSL rating of 1 (Unlimited).

Allowable Variations: Substitution is permitted for packaging format (Tape & Reel vs. Cut Tape) and optional features (Board Lock, Pick and Place capability) without affecting electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full ROHS3 compliance. Selection between SSM-120-L-DV-TR and its substitutes is determined by packaging requirements and assembly process needs:

SSM-120-L-DV-TR (Tape & Reel): Primary specification for high-volume automated assembly operations requiring continuous reel feeding.

SSM-120-L-DV-K-TR (Cut Tape): Suitable for lower-volume production runs or manual assembly processes where individual component handling is required. Includes Pick and Place feature for automated placement compatibility.

SSM-120-L-DV-LC-M-TR (Tape & Reel with Board Lock): Recommended for applications requiring mechanical retention during assembly and test phases. Combines reel packaging with Board Lock and Pick and Place features for enhanced assembly process control.

All three parts are electrically and mechanically interchangeable within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can SSM-120-L-DV-K-TR be used as a direct replacement for SSM-120-L-DV-TR?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: SSM-120-L-DV-TR is supplied in Tape & Reel (TR) format, while SSM-120-L-DV-K-TR is supplied in Cut Tape (CT) format. Selection depends on assembly equipment and volume requirements.

Q: What is the advantage of SSM-120-L-DV-LC-M-TR over the base SSM-120-L-DV-TR?

A: SSM-120-L-DV-LC-M-TR includes Board Lock and Pick and Place features. Board Lock provides mechanical retention during assembly and testing. Both parts maintain identical electrical and core mechanical specifications.

Q: Are all three parts compatible with the same mating connectors?

A: Yes. All three parts are 40-position receptacles with 0.100" (2.54mm) pitch and identical contact geometry. They mate with the same plug connectors from the Tiger Claw™ SSM series.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. No baking or desiccant storage is required.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the PCB assembly process and equipment support the specific packaging format. Electrical performance and mechanical fit are identical across all three part numbers.
