TML-115-01-S-D-SM Equivalent & Substitute Parts

Part Overview

The TML-115-01-S-D-SM is a shrouded rectangular connector header manufactured by Samtec Inc., designed for surface mount board-to-board applications. This 30-position connector operates at 0.050" (1.27mm) pitch with dual-row configuration and 0.100" (2.54mm) row spacing. The component features a 4-wall shrouded design with push-pull fastening and gold-plated mating contacts. Currently in active production status with 1009 units available in inventory, this connector is ROHS3 compliant and suitable for applications requiring reliable surface mount interconnection.

Substitute parts are identified based on matching core electrical and mechanical parameters: connector type, contact configuration, pitch spacing, row count, mounting method, and shrouding design. Alternative sources become necessary when primary inventory is depleted, supply chain constraints occur, or design flexibility permits equivalent connector families.

These parameters establish functional and mechanical interchangeability for board-to-board connector applications requiring 30-position, dual-row, 1.27mm pitch surface mount headers with shrouded design.

Parameter Comparison

Engineering Selection Recommendations

Both the TML-115-01-S-D-SM and 5-104549-5 are active production components with ROHS3 compliance and EAR99 export classification. Selection between these parts is based on the following provided specifications:

TML-115-01-S-D-SM (Samtec) is suitable when:

• Push-pull fastening mechanism is required
• Operating temperature range of -55°C to 125°C is specified
• Square contact geometry is preferred
• Liquid Crystal Polymer (LCP) insulation material is required
• Tube packaging is acceptable

5-104549-5 (TE Connectivity) is suitable when:

• Latch holder fastening mechanism is acceptable
• Operating temperature range of -65°C to 105°C meets application requirements
• Circular contact geometry is acceptable
• Polyphthalamide (PPA) insulation material is acceptable
• UL94 V-0 flammability rating is required
• 30VAC voltage rating specification is needed
• Bulk packaging is acceptable
• Higher inventory availability (162900 units) is advantageous

Both connectors share identical pitch, position count, row spacing, shrouding configuration, and surface mount termination method, establishing mechanical and electrical interchangeability for standard board-to-board applications.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if 5-104549-5 can substitute for TML-115-01-S-D-SM?

A: The critical parameters are: 0.050" (1.27mm) mating pitch, 30 positions, 2 rows, 0.100" (2.54mm) row spacing, shrouded 4-wall design, surface mount termination, male pin contacts, and solder termination. Both parts match these specifications exactly.

Q: What are the differences between these two connectors?

A: Key differences include: contact shape (square vs. circular), insulation material (LCP vs. PPA), fastening type (push-pull vs. latch holder), operating temperature range (-55°C to 125°C vs. -65°C to 105°C), insulation height (0.380" vs. 0.435"), contact length (0.120" vs. 0.125"), and packaging format (tube vs. bulk). The TE Connectivity part includes specified voltage rating (30VAC) and flammability rating (UL94 V-0).

Q: Are there any compatibility concerns when substituting these parts?

A: Physical dimensions differ slightly in insulation height and contact length. PCB layout and mating connector design must accommodate the 5-104549-5's 0.435" insulation height versus the TML-115-01-S-D-SM's 0.380" height. Fastening mechanism differences (push-pull vs. latch holder) require verification with mating connector specifications. Operating temperature ranges differ; applications requiring -55°C operation must use the Samtec part.

Q: What is the difference between push-pull and latch holder fastening?

A: Push-pull fastening (TML-115-01-S-D-SM) uses a push-to-connect, pull-to-disconnect mechanism. Latch holder fastening (5-104549-5) uses a latching mechanism for secure connection. These are mechanically distinct and require compatible mating connectors.

Q: Can I use the TE Connectivity part in applications requiring -55°C operation?

A: No. The 5-104549-5 operates from -65°C to 105°C, which does not cover the -55°C to 125°C range of the TML-115-01-S-D-SM. For applications requiring -55°C minimum operation, the Samtec part is required.

Q: What packaging considerations apply to these parts?

A: The TML-115-01-S-D-SM is supplied in tube packaging (1009 units available). The 5-104549-5 is supplied in bulk packaging with significantly higher inventory (162900 units available). Bulk packaging may require different handling and storage procedures.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TML-115-01-S-D-SM and 5-104549-5 are ROHS3 compliant and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.
