Winchester Interconnect 2029-15-9 BNC Jack-to-Jack Coaxial Adapter: Equivalent & Substitute Parts

Part Overview

The Winchester Interconnect 2029-15-9 is an active, in-stock coaxial adapter connector designed for RF applications requiring female-to-female BNC jack connections at 75 ohms impedance. This straight-mounted, free-hanging adapter facilitates connection between two BNC female sockets using bayonet locking mechanisms. The part is manufactured from brass with nickel finish and beryllium copper center contacts, rated for 500 mating cycles across an operating temperature range of -65°C to 165°C. Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters while remaining in active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Winchester Interconnect 2029-15-9 is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Jack to Jack
• Adapter Series: BNC to BNC
• Center Gender: Female to Female
• Impedance: 75 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Center Contact Plating: Gold
• Dielectric Material: PTFE
• Product Status: Active

Allowable Variations:

• Manufacturer identity (different OEM acceptable)
• Body finish (provided core material is brass)
• Mating cycle ratings (equal to or exceeding 500 cycles)
• Operating temperature range (must encompass or equal the specified range)
• Packaging format (bulk or other configurations)

The substitute parts identified—Pomona Electronics 3283 and Pomona Electronics 6737—are evaluated against these criteria. Part 6737 qualifies as a direct equivalent. Part 3283 does not qualify due to impedance mismatch (50 ohms versus 75 ohms required).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent:

Pomona Electronics 6737 is the qualified equivalent substitute for Winchester Interconnect 2029-15-9. Both parts maintain identical impedance (75 ohms), adapter configuration (BNC jack-to-jack, female-to-female), and core material specifications (brass body, nickel finish, beryllium copper center contacts, PTFE dielectric). Both are rated for 500 mating cycles and operate across overlapping temperature ranges. Pomona 6737 carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. The maximum frequency specification of 3 GHz for Pomona 6737 is provided; Winchester 2029-15-9 does not specify this parameter. Both parts are active products with substantial inventory availability.

Non-Equivalent Substitute:

Pomona Electronics 3283 does not qualify as a substitute due to impedance specification of 50 ohms, which differs from the required 75 ohms. Although this part shares identical adapter type, connector series, gender configuration, style, mounting type, fastening mechanism, and dielectric material, the impedance mismatch prevents functional equivalence in 75-ohm RF systems.

Frequently Asked Questions (FAQ)

Q: Can Pomona Electronics 3283 be used in place of Winchester 2029-15-9?

A: No. Pomona 3283 is specified at 50 ohms impedance, while Winchester 2029-15-9 is specified at 75 ohms. Impedance is a critical electrical parameter that determines signal integrity and reflection characteristics in RF systems. Substitution across different impedance values is not permitted.

Q: What is the primary difference between Winchester 2029-15-9 and Pomona 6737?

A: Both parts are functionally equivalent at 75 ohms impedance with identical mechanical and electrical specifications. The primary differences are manufacturer identity and maximum operating temperature: Winchester 2029-15-9 operates to 165°C, while Pomona 6737 operates to 155°C. Pomona 6737 additionally specifies a maximum frequency of 3 GHz and carries ROHS3 compliance certification.

Q: Are there packaging differences between these parts?

A: Winchester 2029-15-9 packaging is not specified in available data. Pomona 3283 and Pomona 6737 are supplied in bulk packaging. Packaging format does not affect functional compatibility.

Q: Do all three parts use the same dielectric material?

A: Yes. Winchester 2029-15-9, Pomona 3283, and Pomona 6737 all use polytetrafluoroethylene (PTFE) as the dielectric material.

Q: What is the mating cycle rating for Pomona 3283?

A: Mating cycle rating for Pomona 3283 is not specified in available data. Winchester 2029-15-9 and Pomona 6737 are both rated for 500 mating cycles.

Q: Are these parts RoHS compliant?

A: RoHS compliance status for Winchester 2029-15-9 is not specified. Pomona Electronics 3283 and Pomona Electronics 6737 are both ROHS3 compliant and REACH unaffected.
