Substitute Part Grouping Explanation
Substitute parts for the TSW-104-25-T-S are identified based on the following critical parameters that determine functional equivalence:
- Pitch - Mating: 0.100" (2.54mm)
- Number of Positions: 4
- Number of Rows: 1
- Connector Type: Header
- Contact Type: Male Pin
- Mounting Type: Through Hole
- Termination: Solder
- Operating Temperature: -55°C ~ 105°C

Engineering Selection Recommendations
All three parts maintain active product status and full ROHS3 compliance. The TSW-104-25-T-S, HTSW-104-25-T-S, and HTSW-104-25-TM-S are functionally equivalent within the specified parameter set. Selection between these parts may be based on inventory availability, lead time, or packaging requirements, as all meet identical electrical and mechanical specifications for through-hole 4-position 2.54mm pitch header applications.
Frequently Asked Questions (FAQ)
Q: Can HTSW-104-25-T-S or HTSW-104-25-TM-S be used as direct replacements for TSW-104-25-T-S?
A: Yes. All three parts share identical pitch (0.100" / 2.54mm), position count (4), row configuration (1), contact geometry, mounting type (through hole), and operating temperature range (-55°C ~ 105°C). All are ROHS3 compliant and UL94 V-0 rated.
Q: What is the difference between the substitute parts?
A: HTSW-104-25-T-S and HTSW-104-25-TM-S differ from TSW-104-25-T-S in insulation material (Liquid Crystal Polymer versus Polybutylene Terephthalate) and insulation color (Natural versus Black). These variations do not affect electrical or mechanical compatibility.
Q: Are there any compatibility concerns when substituting these parts?
A: No compatibility concerns exist within the specified parameter set. All parts feature identical contact length, contact material (Phosphor Bronze), contact finish (Tin), and solder termination specifications.
Q: What is the Moisture Sensitivity Level (MSL) difference?
A: TSW-104-25-T-S carries MSL 1 (Unlimited). HTSW-104-25-T-S and HTSW-104-25-TM-S are listed as Not Applicable for MSL. This does not affect functional performance in standard storage and handling conditions.
Q: Can these parts be used interchangeably in PCB designs?
A: Yes. All three parts maintain identical through-hole mounting specifications, contact spacing, and overall dimensions. PCB footprints designed for one part accommodate all three without modification.
