Parameter Comparison

Engineering Selection Recommendations

Both the TMMH-150-01-G-D and M22-2025005 are active products with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Selection between these parts should be based on the following considerations:

The TMMH-150-01-G-D supports an extended operating temperature range of -55°C to 125°C, making it suitable for applications requiring operation at extreme low temperatures or sustained high-temperature environments.

The M22-2025005 operates within -40°C to 105°C and includes specified current rating (1A per contact) and defined mated stacking heights (3.8mm, 5.9mm, 8.6mm), providing additional mechanical specification clarity for applications with stacking requirements.

Both parts maintain identical electrical and mechanical pitch specifications, contact configuration, and termination method, ensuring functional interchangeability in standard board-to-board connector applications where operating temperature requirements fall within the overlapping range of -40°C to 105°C.

Frequently Asked Questions (FAQ)

Q: What determines if M22-2025005 can replace TMMH-150-01-G-D?

A: Functional equivalence is established through matching connector type (Header, Cuttable), contact type (Male Pin), position count (100), row configuration (2 rows), mating pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), mounting method (Through Hole), termination type (Solder), contact material (Phosphor Bronze), and mating contact finish (Gold). Both parts satisfy these criteria.

Q: Are there operating temperature limitations when substituting?

A: The TMMH-150-01-G-D operates from -55°C to 125°C, while the M22-2025005 operates from -40°C to 105°C. Applications requiring temperatures below -40°C or above 105°C must use the TMMH-150-01-G-D. For applications within the -40°C to 105°C range, both parts are suitable.

Q: What are the physical dimension differences?

A: Contact length specifications differ between parts. The TMMH-150-01-G-D has overall contact length of 0.302" (7.67mm) with insulation height of 0.079" (2.00mm). The M22-2025005 has overall contact length of 0.331" (8.40mm) with insulation height of 0.059" (1.50mm). These differences may affect PCB layout and mating connector selection.

Q: Are both parts RoHS compliant?

A: Yes, both TMMH-150-01-G-D and M22-2025005 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the inventory status for each part?

A: TMMH-150-01-G-D has 900 pieces in stock. M22-2025005 has 1358 pieces in stock. Both are available as new original components in bulk packaging.
