SSW-148-02-S-D Equivalent & Substitute Parts

Part Overview

The SSW-148-02-S-D is a 96-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch spacing. This connector features gold-plated mating contacts, through-hole solder termination, and push-pull fastening. The part is currently active in production with 817 units in stock.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when procurement lead times are extended, or when design flexibility allows for functionally compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-148-02-S-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle, 96 positions, 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Electrical Performance: 4.7A per contact current rating
• Contact System: Forked contact type with gold mating finish at 30.0µin thickness
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Environmental Compliance: UL94 V-0 flammability rating, operating range -55°C to 125°C
• Material & Regulatory: Liquid Crystal Polymer insulation, ROHS3 compliance, MSL 1

The substitute part identified maintains identical specifications across all these parameters, ensuring direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The substitute part SSW-148-02-S-D is electrically and mechanically equivalent to the main part across all specified parameters. Both parts are manufactured by Samtec Inc. within the SSW series and maintain identical connector architecture, contact specifications, and environmental ratings.

The primary distinction is product status: the main part is active in production, while the substitute is discontinued at DiGi Electronics. For applications requiring long-term availability and supply chain stability, the active production part is preferred. However, the substitute remains functionally compatible for immediate procurement needs where existing inventory is available.

Both parts satisfy ROHS3 compliance and REACH requirements. The MSL 1 rating indicates unlimited shelf life under standard storage conditions. The UL94 V-0 flammability rating and operating temperature range of -55°C to 125°C are maintained across both variants.

Frequently Asked Questions (FAQ)

Q: Are these parts pin-compatible? A: Yes. Both parts are 96-position receptacles with identical 0.100" (2.54mm) pitch spacing, row configuration, and contact arrangement. They are directly interchangeable at the PCB level.

Q: What is the difference between the main part and the substitute? A: The electrical and mechanical specifications are identical. The substitute is discontinued at DiGi Electronics while the main part remains in active production. Inventory levels differ slightly (746 units versus 817 units).

Q: Can I use the substitute in a new design? A: The substitute is functionally equivalent and meets all specified compliance requirements. However, since it is discontinued, it is not suitable for designs requiring long-term production support or future procurement.

Q: Are the contact finishes identical? A: Yes. Both parts feature gold-plated mating contacts with 30.0µin (0.76µm) thickness and tin-plated posts, ensuring equivalent electrical performance and reliability.

Q: What is the current-carrying capacity? A: Each contact is rated for 4.7A. With 96 positions, the total current capacity depends on the number of positions used and the circuit design.

Q: Are there any temperature or environmental limitations? A: Both parts operate across -55°C to 125°C and maintain UL94 V-0 flammability compliance. MSL 1 rating indicates no moisture sensitivity restrictions during storage or handling.

Q: What mounting method is required? A: Both parts use through-hole solder termination. They are designed for direct PCB mounting with standard wave or reflow soldering processes.
