Substitute Part Grouping Explanation

Substitution of the 76308-207 is determined by the following critical parameters:

Connector Type: Receptacle (female socket)
Number of Positions: 7
Pitch - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole
Termination: Solder
Fastening Type: Push-Pull
Style: Board to Board

Substitute parts must match these core parameters to ensure mechanical and electrical compatibility. Contact finish (gold vs. tin), contact material composition, insulation material, and post length variations are secondary parameters that define specific substitute variants within compatible families.

Engineering Selection Recommendations

Primary Substitute (Exact Match): Molex 0901471107 provides direct functional equivalence as a 7-position receptacle with 0.100" pitch, through-hole solder termination, and push-pull fastening. This part is active and ROHS3 compliant, addressing the obsolescence of the 76308-207. Contact finish differs (tin vs. gold), which may affect corrosion resistance in specific environments.

Gold-Plated Alternatives: Samtec ESS-107 series (ESS-107-G-03, ESS-107-G-23, ESS-107-G-26, ESS-107-T-06, ESS-107-T-08, ESS-107-T-23, ESS-107-T-26, ESS-107-T-28) maintain gold mating contact finish and elevated socket design. These parts are active, ROHS3 compliant, and support extended operating temperature ranges (-55°C to 125°C). Post length variations accommodate different PCB stack-up requirements.

Position-Reduced Alternative: Amphenol ICC 77311-118-03LF is a 3-position header variant with identical pitch and termination. This part is suitable only for applications requiring fewer than 7 positions and represents a different connector type (header vs. receptacle).

Compliance Consideration: The original 76308-207 is RoHS non-compliant. All active substitutes listed are RoHS3 compliant, supporting modern procurement and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901471107 directly replace the Amphenol ICC 76308-207?

A: The Molex 0901471107 matches all critical parameters: 7-position receptacle, 0.100" pitch, through-hole solder termination, and push-pull fastening. The primary difference is mating contact finish (tin vs. gold). Compatibility depends on application requirements for contact resistance and corrosion performance.

Q: What is the difference between Samtec ESS-107 variants?

A: Samtec ESS-107 variants differ in post length (contact length extending from the insulation body). Designations such as ESS-107-G-03, ESS-107-G-23, ESS-107-G-26, ESS-107-T-08, ESS-107-T-23, ESS-107-T-26, and ESS-107-T-28 indicate specific post lengths ranging from 0.123" to 0.373". Selection depends on PCB thickness and mating header height. The "G" suffix indicates gold post finish; "T" indicates tin post finish.

Q: Why is the Amphenol ICC 77311-118-03LF listed as a substitute if it has only 3 positions?

A: The 77311-118-03LF is listed as a substitute only for applications requiring 3 positions or fewer. It shares identical pitch (0.100"), mounting type (through-hole), termination (solder), and fastening (push-pull) with the 76308-207. This part is not a direct replacement for 7-position applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts listed (Molex 0901471107, Samtec ESS-107 series, and Amphenol ICC 77311-118-03LF) are RoHS3 compliant. The original 76308-207 is RoHS non-compliant.

Q: What operating temperature range should I consider for new designs?

A: The original 76308-207 does not specify an operating temperature range. Molex 0901471107 operates from -55°C to 105°C. Samtec ESS-107 series and Amphenol ICC 77311-118-03LF support -55°C to 125°C and -65°C to 125°C respectively. Select based on application thermal requirements.

Q: Does contact finish affect electrical performance?

A: Contact finish (gold vs. tin) affects contact resistance and corrosion resistance. Gold provides superior corrosion resistance and lower contact resistance over extended service life. Tin offers cost efficiency for non-corrosive environments. Selection depends on application environment and reliability requirements.
