TSW-113-07-F-D-LL Equivalent & Substitute Parts

Part Overview

The TSW-113-07-F-D-LL is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 26-position, 2-row connector operates across the temperature range of -55°C to 125°C and features gold-plated mating contacts with tin-plated solder posts. The part is currently active in production and ROHS3 compliant.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design specifications allow for compatible alternatives from different manufacturers that meet the same electrical and mechanical interface requirements.

Substitute Part Grouping Explanation

Substitution for the TSW-113-07-F-D-LL is determined by strict equivalence in the following critical parameters:

Number of positions: 26
Number of rows: 2
Pitch - mating: 0.100" (2.54mm)
Row spacing - mating: 0.100" (2.54mm)
Contact type: Male Pin
Mounting type: Through Hole
Connector type: Header
Fastening type: Push-Pull
Contact shape: Square
Insulation color: Black
Material flammability rating: UL94 V-0
Moisture sensitivity level: 1 (Unlimited)

Substitute parts are grouped into two categories based on contact post length variations, which affect overall connector height and PCB stack-up compatibility:

Group A (Post Length 0.095" - 0.100"): Parts with shorter post lengths suitable for standard PCB applications.

Group B (Post Length 0.120" - 0.150"): Parts with extended post lengths for applications requiring greater solder joint length or elevated PCB mounting.

All substitute parts maintain the same mating interface geometry, allowing direct functional replacement in board-to-board or cable connection applications.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

Parts 67996-126HLF, 67997-126HLF, 67997-226HLF, 67997-426HLF, 77313-101-26LF, and 77313-118-26LF are all active products with RoHS compliance. Selection among these depends on contact post length requirements for your PCB stack-up and solder joint geometry.

For applications requiring post length matching closest to the original 0.100" specification, 67996-126HLF and 77313-101-26LF provide 0.095" posts. For extended post lengths, 67997-126HLF, 67997-226HLF, 67997-426HLF, and 77313-118-26LF offer 0.120" posts.

Extended Temperature Range Option:

Parts 67997-126HLF, 67997-226HLF, 67997-426HLF, 68602-126HLF, 75844-150-26LF, and 77313-118-26LF support operating temperatures to 130°C, exceeding the original part's 125°C maximum.

Contact Finish Considerations:

Gold-plated mating contacts (67996-126HLF, 67997-126HLF, 67997-226HLF, 77313-101-26LF, 77313-118-26LF, 68602-126HLF) maintain the original gold finish specification. Tin-plated alternatives (67996-426HLF, 67997-426HLF) are available for cost-sensitive applications.

Avoid in New Designs:

Part 75844-150-26LF carries obsolete product status and should not be selected for new designs, despite ROHS3 compliance and active inventory.

TE Connectivity Alternative:

Part 6-146256-3 from TE Connectivity provides an alternative from a different manufacturer ecosystem. This part operates at a reduced maximum temperature of 105°C and uses copper alloy contacts instead of phosphor bronze, making it suitable only for applications within this narrower temperature range.

Frequently Asked Questions (FAQ)

Q: Can I substitute TSW-113-07-F-D-LL with any of these parts directly on my PCB?

A: Direct substitution depends on your PCB design. All listed parts maintain the same 26-position, 2-row, 2.54mm pitch mating interface. However, contact post length varies from 0.095" to 0.150", which affects solder joint length and PCB stack-up height. Verify your PCB design accommodates the post length of your selected substitute.

Q: What is the difference between parts with different contact post lengths?

A: Contact post length determines how far the solder pins extend below the connector body. Shorter posts (0.095") are suitable for standard PCB applications. Longer posts (0.120" to 0.150") provide extended solder joint length, beneficial for high-reliability applications or when additional mechanical support is required.

Q: Are all substitute parts RoHS compliant?

A: All listed active parts carry RoHS compliance (either ROHS3 or RoHS). Part 75844-150-26LF is ROHS3 compliant but carries obsolete status. TE Connectivity part 6-146256-3 is ROHS3 compliant.

Q: What is the difference between gold and tin contact finishes?

A: Gold-plated mating contacts (30.0µin or 15.0µin thickness) provide superior corrosion resistance and lower contact resistance. Tin-plated contacts offer cost reduction for applications where corrosion resistance requirements are less stringent. Both finishes are suitable for standard board-to-board connections.

Q: Can I use part 75844-150-26LF as a substitute?

A: Part 75844-150-26LF is electrically and mechanically compatible but carries obsolete product status. For new designs, select from active parts: 67996-126HLF, 67997-126HLF, 67997-226HLF, 67997-426HLF, 77313-101-26LF, or 77313-118-26LF.

Q: Which substitute offers the closest match to the original TSW-113-07-F-D-LL?

A: Parts 67996-126HLF and 77313-101-26LF provide the closest dimensional match with 0.095" contact post length, compared to the original 0.100" specification. Both are active products with full RoHS compliance and phosphor bronze contacts with gold mating finish.

Q: What packaging formats are available?

A: The original TSW-113-07-F-D-LL is supplied in bulk packaging. Amphenol ICC (FCI) substitutes are available in bag packaging (67996-126HLF, 67996-426HLF, 67997-126HLF, 67997-226HLF, 67997-426HLF, 68602-126HLF, 75844-150-26LF) or bulk packaging (77313-101-26LF, 77313-118-26LF). TE Connectivity part 6-146256-3 is supplied in bulk packaging.

Q: Does contact material affect compatibility?

A: All substitute parts use either phosphor bronze or copper alloy contacts, both suitable for standard board-to-board connections. Phosphor bronze (used in Samtec and most Amphenol parts) and copper alloy (TE Connectivity 6-146256-3) provide equivalent electrical performance for this connector class.
