Substitute Part Grouping Explanation

Substitute parts for the HTST-105-01-S-DV-A-P-TR are qualified based on the following critical parameters that must match or be compatible:

Connector type: Header
Contact type: Male pin
Pitch - mating: 0.100" (2.54mm)
Number of positions: 10
Number of rows: 2
Row spacing - mating: 0.100" (2.54mm)
Mounting type: Surface mount
Shrouding: Shrouded - 4 wall
Termination: Solder
Fastening type: Push-pull
Contact shape: Square
Contact finish - mating: Gold
Material flammability rating: UL94 V-0

The identified substitutes meet these core electrical and mechanical parameters. Variations in contact length, insulation height, current rating, operating temperature range, and insulation material are secondary parameters that may differ between the main part and substitutes while maintaining functional compatibility in most applications.

Engineering Selection Recommendations

All three parts maintain active production status and comply with UL94 V-0 flammability requirements. The HTST-105-01-S-DV-A-P-TR and N2510-6V0C-RB-WD both carry REACH Unaffected status, while the 72454-010LF is REACH Affected. All parts are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

The HTST-105-01-S-DV-A-P-TR provides the highest current rating at 3.4A per contact and the widest operating temperature range (-55°C to 125°C). The 72454-010LF offers the lowest current rating at 1A with an extended low-temperature operating range (-65°C). The N2510-6V0C-RB-WD provides intermediate current rating at 1.75A with operating range of -55°C to 105°C.

Selection between these parts should be based on application-specific current requirements, operating temperature constraints, and supply chain availability. All parts share identical pitch, position count, row configuration, mounting type, shrouding, termination, and fastening characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 72454-010LF substitute for the HTST-105-01-S-DV-A-P-TR in high-current applications?

A: The 72454-010LF has a maximum current rating of 1A per contact, compared to 3.4A for the HTST-105-01-S-DV-A-P-TR. Substitution is not suitable for applications requiring current above 1A per contact.

Q: What is the difference in operating temperature range between these parts?

A: The HTST-105-01-S-DV-A-P-TR operates from -55°C to 125°C. The 72454-010LF operates from -65°C to 105°C. The N2510-6V0C-RB-WD operates from -55°C to 105°C. Selection depends on specific application temperature requirements.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical pitch (0.100"), position count (10), row configuration (2 rows), mounting type (surface mount), shrouding (4-wall), termination (solder), and fastening type (push-pull). Mechanical interchangeability is confirmed.

Q: What packaging formats are available for these parts?

A: The HTST-105-01-S-DV-A-P-TR is supplied in Tape & Reel (TR) packaging. The 72454-010LF is supplied in Tray packaging. The N2510-6V0C-RB-WD is supplied in Cut Tape (CT) & Digi-Reel® packaging.

Q: Do all parts meet the same regulatory compliance standards?

A: All three parts are UL94 V-0 rated and RoHS compliant. The HTST-105-01-S-DV-A-P-TR and N2510-6V0C-RB-WD are REACH Unaffected. The 72454-010LF is REACH Affected. All parts carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the contact material difference between the HTST-105-01-S-DV-A-P-TR and N2510-6V0C-RB-WD?

A: The HTST-105-01-S-DV-A-P-TR uses Phosphor Bronze contacts. The N2510-6V0C-RB-WD uses Copper Alloy contacts. Both materials are suitable for the specified contact finish and current ratings.
