TSW-118-08-SS-D Equivalent & Substitute Parts

Part Overview

The TSW-118-08-SS-D is a Classic PCB Header Strip manufactured by Samtec Inc., classified as a rectangular connector for through-hole mounting applications. This 36-position, 2-row header connector operates at 0.100" (2.54mm) pitch and is designed for board-to-board or cable interconnection. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or inventory constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-118-08-SS-D is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 36
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Insulation Material: Polybutylene Terephthalate (PBT)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute part PRPC018DAAN-RC (Sullins Connector Solutions) satisfies all mandatory parameters. Variations in contact length, contact finish thickness, operating temperature range, and post contact material do not preclude substitution when the primary part is unavailable, provided the application requirements fall within the substitute's specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TSW-118-08-SS-D remains the preferred selection when available. It provides an extended operating temperature range (-55°C to 125°C) and phosphor bronze contact material, supporting applications requiring broader thermal performance.

Substitute Part Selection: The PRPC018DAAN-RC is a valid substitute when the TSW-118-08-SS-D is unavailable. Both parts maintain Active product status and ROHS3 compliance. The substitute is suitable for applications operating within -40°C to 105°C. The shorter post contact length (0.120" versus 0.200") and brass contact material (versus phosphor bronze) do not affect electrical or mechanical compatibility for standard board-to-board interconnection applications. The substitute specifies a 3A per contact current rating, providing defined electrical performance.

Compliance Verification: Both parts satisfy UL94 V-0 flammability requirements and ROHS3 environmental compliance. No additional certification review is required for standard industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can PRPC018DAAN-RC replace TSW-118-08-SS-D in all applications?

A: PRPC018DAAN-RC is mechanically and electrically compatible for applications operating within -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must use the original TSW-118-08-SS-D, which supports -55°C to 125°C.

Q: What is the difference in contact post length between these parts?

A: The TSW-118-08-SS-D has a 0.200" (5.08mm) post contact length, while PRPC018DAAN-RC has a 0.120" (3.05mm) post contact length. Both are suitable for standard through-hole PCB mounting with typical board thickness of 0.062" (1.57mm).

Q: Are the contact materials interchangeable?

A: The TSW-118-08-SS-D uses phosphor bronze contacts; PRPC018DAAN-RC uses brass contacts. Both materials are suitable for gold-plated mating surfaces and standard signal/power distribution applications. Contact material selection does not affect substitution eligibility for equivalent electrical performance.

Q: Do both parts have the same pitch and row spacing?

A: Yes. Both parts maintain 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing. They are mechanically interchangeable in PCB layouts designed for standard 0.100" header spacing.

Q: What is the current rating for each part?

A: The TSW-118-08-SS-D does not specify a current rating in the provided data. The PRPC018DAAN-RC specifies 3A per contact. For applications requiring current rating verification, consult the manufacturer's detailed datasheet.

Q: Are both parts RoHS compliant?

A: Yes. Both TSW-118-08-SS-D and PRPC018DAAN-RC are ROHS3 compliant and suitable for applications subject to RoHS environmental regulations.

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

A: Yes, provided the application operates within the substitute's temperature range (-40°C to 105°C) and does not require the extended low-temperature performance of the original part. PCB layout and connector footprint compatibility is maintained due to identical pitch, row spacing, and position count.
