SSW-109-01-S-S Equivalent & Substitute Parts

Part Overview

The SSW-109-01-S-S is a 9-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts, forked contact geometry, and push-pull fastening. The part is currently active in production with 1017 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative contact geometries or insulation materials.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-109-01-S-S is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Receptacle
• Number of positions: 9
• Mating pitch: 0.100" (2.54mm)
• Mounting type: Through hole
• Termination method: Solder
• Fastening type: Push-pull
• Mating contact finish: Gold at 30.0µin (0.76µm)

Secondary Compatibility Factors:

• Operating temperature range (minimum -55°C required)
• Current rating per contact (minimum 2A acceptable)
• Insulation material and color
• Contact geometry (forked or female socket acceptable)
• Flammability rating and RoHS compliance

The identified substitutes meet all primary matching criteria. Variations in contact post finish, insulation material composition, and contact length do not preclude substitution when the mating interface and electrical performance remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

534237-7 (TE Connectivity AMP Connectors): This substitute maintains full electrical and mechanical compatibility with the SSW-109-01-S-S at the mating interface. The connector is ROHS3 compliant and carries REACH Affected status. The female socket contact geometry differs from the forked design of the original part but provides equivalent mating performance. Operating temperature range extends to -65°C, exceeding the original specification. Current rating of 2A per contact is lower than the original 4.7A specification; this substitute is suitable only for applications where the actual current demand does not exceed 2A per contact. Insulation height variation of 0.005" (0.13mm) and contact post length difference of 0.011" (0.28mm) are within typical PCB layout tolerances for through-hole applications.

929850-01-09-RB (3M): This substitute provides equivalent mating interface performance with forked contact geometry matching the original design. The connector is RoHS compliant and REACH Unaffected. Operating temperature range of -40°C ~ 105°C is narrower than the original specification; this substitute is suitable only for applications operating within this temperature window. Current rating of 2A per contact is lower than the original 4.7A specification; this substitute is suitable only for applications where the actual current demand does not exceed 2A per contact. Voltage rating of 1500V is specified for this part. Insulation height is 0.010" (0.25mm) lower than the original, and contact post length is 0.021" (0.54mm) longer; these dimensional variations require verification against specific PCB layout requirements.

Both substitutes are active products with established supply availability. Selection between substitutes and the original part should be based on current rating requirements, operating temperature range, and specific PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the 534237-7 be used as a direct replacement for the SSW-109-01-S-S?

A: The 534237-7 provides equivalent mating interface performance and is mechanically compatible for through-hole PCB mounting. However, the current rating of 2A per contact is lower than the original 4.7A specification. Use this substitute only in applications where the actual current per contact does not exceed 2A. Insulation height and contact post length differ slightly; verify these dimensions against your specific PCB layout.

Q: What is the key difference between the contact geometries?

A: The SSW-109-01-S-S and 929850-01-09-RB both use forked contact geometry. The 534237-7 uses female socket contacts. Both geometries are compatible with standard 0.100" (2.54mm) pitch male pins and provide equivalent electrical performance at the mating interface.

Q: Are there temperature limitations with the substitute parts?

A: The 534237-7 operates from -65°C to 125°C, exceeding the original -55°C to 125°C range. The 929850-01-09-RB operates from -40°C to 105°C, which is narrower than the original specification. Select the 929850-01-09-RB only for applications operating within -40°C to 105°C.

Q: What is the current rating difference, and does it matter?

A: The SSW-109-01-S-S is rated at 4.7A per contact, while both substitutes are rated at 2A per contact. Use substitutes only in applications where the actual current per contact does not exceed 2A. For higher current applications, the original SSW-109-01-S-S is required.

Q: How do the insulation materials differ?

A: The SSW-109-01-S-S uses Liquid Crystal Polymer (LCP). The 534237-7 uses polyester with glass filler. The 929850-01-09-RB uses PCT and polyester with glass filler. All materials are suitable for standard through-hole PCB applications. Material selection may affect mechanical properties and environmental resistance; verify compatibility with your specific application environment.

Q: What are the packaging differences?

A: The SSW-109-01-S-S and 929850-01-09-RB are supplied in bulk packaging. The 534237-7 is supplied in tube packaging. Packaging does not affect electrical or mechanical performance; it affects handling, storage, and inventory management.

Q: Are there RoHS and REACH compliance considerations?

A: All three parts are RoHS compliant. The SSW-109-01-S-S and 929850-01-09-RB are REACH Unaffected. The 534237-7 is REACH Affected. For applications requiring REACH Unaffected status, use the SSW-109-01-S-S or 929850-01-09-RB.

Q: What are the dimensional tolerances for insulation height and contact post length?

A: Insulation height varies by 0.005" to 0.010" across the three parts. Contact post length varies by 0.011" to 0.021". These variations are within typical PCB layout tolerances for through-hole connectors but should be verified against your specific PCB design, particularly for applications with tight vertical clearance or specific solder joint geometry requirements.
