Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-150-12-S-D is determined by the following invariant parameters that must remain constant across all substitute parts:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 100
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Shrouded - 4 Wall
• Contact Length - Mating: 0.139" (4.63mm)
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C
• Current Rating: 2.9A per Contact
• Voltage Rating: 275VAC
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts vary in two parameters:

1. Insulation Height: The TFM-150-12-S-D has an insulation height of 0.290" (7.37mm). Substitutes include variants with 0.360" (9.14mm) or 0.435" (11.05mm) insulation heights to accommodate different PCB stackup requirements.

2. Features: The main part has no board guide or lock feature. Substitutes include variants with Board Guide or Board Lock features for enhanced mechanical alignment and retention.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status with ROHS3 compliance and identical electrical ratings. Selection between the TFM-150-12-S-D and its substitutes depends on mechanical design requirements:

For designs with standard PCB stackup and no mechanical alignment constraints, the TFM-150-12-S-D or TFM-150-12-S-D-LC provide the minimum insulation height of 0.290" (7.37mm). The TFM-150-12-S-D-LC adds Board Lock retention for applications requiring enhanced mating security.

For designs requiring increased insulation height to accommodate thicker PCB assemblies or additional component clearance, the TFM-150-22-S-D-A and TFM-150-22-S-D-LC variants provide 0.360" (9.14mm) insulation height. The TFM-150-22-S-D-A includes Board Guide alignment features, while TFM-150-22-S-D-LC includes Board Lock retention.

For maximum insulation height applications, the TFM-150-32-S-D-A and TFM-150-32-S-D-LC variants provide 0.435" (11.05mm) insulation height. The TFM-150-32-S-D-A includes Board Guide alignment, while TFM-150-32-S-D-LC includes Board Lock retention. The TFM-150-32-S-D-LC variant has the highest inventory availability at 3096 pieces.

Frequently Asked Questions (FAQ)

Q: Can I substitute TFM-150-12-S-D with a different insulation height variant?

A: Yes. All variants maintain identical electrical specifications (2.9A per contact, 275VAC rating), contact pitch (0.050" / 1.27mm), and operating temperature range (-55°C to 125°C). Substitution is valid when PCB stackup and mechanical clearance accommodate the different insulation heights.

Q: What is the difference between Board Guide and Board Lock features?

A: Both features provide mechanical enhancement beyond the base connector. Board Guide (variants ending in -A) provides alignment assistance during mating. Board Lock (variants ending in -LC) provides positive retention after mating. Selection depends on application requirements for alignment precision versus mating security.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed parts including TFM-150-12-S-D, TFM-150-12-S-D-LC, TFM-150-22-S-D-A, TFM-150-22-S-D-LC, TFM-150-32-S-D-A, and TFM-150-32-S-D-LC are ROHS3 compliant with UL94 V-0 flammability rating.

Q: What is the moisture sensitivity level for these connectors?

A: All parts have Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.

Q: Can I use these connectors in high-temperature applications?

A: Yes. All variants are rated for operating temperatures from -55°C to 125°C, suitable for industrial and automotive applications within this range.

Q: What is the contact material and finish specification?

A: All variants use phosphor bronze contacts with gold plating (30.0µin / 0.76µm thickness) on mating surfaces and tin finish on solder posts, ensuring reliable electrical connection and solderability.
