Key Parameters

Substitute Part Grouping Explanation

Equivalent and substitute parts for the Winchester Interconnect 1329505 are determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Jack to Jack
• Adapter Series: SMA to N
• Center Gender: Female to Female
• Convert From: N Jack, Female Socket
• Convert To: SMA Jack, Female Socket
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded, Threaded

Allowable Variation Parameters:

• Frequency - Max: May exceed 1 GHz
• Body Material: May differ (Brass, Beryllium Copper)
• Body Finish: May differ (Nickel, Gold)
• Center Contact Material: May differ (Brass, Beryllium Copper)
• Dielectric Material: May differ (not specified, PTFE)

Substitute parts must maintain identical mechanical and electrical interface specifications while allowing for enhanced performance characteristics and material composition variations.

Parameter Comparison

Engineering Selection Recommendations

Winchester Interconnect 1329505: Select this part for applications operating within 1 GHz frequency range with operating temperatures between -55°C and 100°C. RoHS Compliant status ensures regulatory compliance for restricted substance requirements. Suitable for standard RF interconnection applications with moderate frequency demands.

Pomona Electronics 4299: This substitute provides extended frequency performance to 12.4 GHz and expanded operating temperature range (-65°C ~ 165°C). Beryllium Copper construction with gold plating offers enhanced durability and signal integrity for high-frequency applications. REACH Affected status requires verification against specific regulatory requirements. Conversion direction is reversed (SMA to N instead of N to SMA).

Cal Test Electronics CT3389: This substitute matches the Winchester 1329505 conversion direction (N to SMA) and provides extended frequency performance to 11 GHz. ROHS3 Compliant and REACH Unaffected status provides regulatory flexibility. Operating temperature range (0°C ~ 50°C) is more restrictive than the main part. Suitable for applications requiring higher frequency performance within standard environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can Pomona Electronics 4299 be used as a direct replacement for Winchester 1329505?

A: The Pomona Electronics 4299 maintains identical mechanical and electrical interface specifications (Jack to Jack, Female to Female, 50 Ohms, Straight, Threaded fastening). However, the conversion direction is reversed: 4299 converts SMA to N, while 1329505 converts N to SMA. Both are functionally equivalent for RF interconnection but must be oriented correctly in the circuit. The 4299 provides superior frequency performance (12.4 GHz vs 1 GHz) and extended operating temperature range.

Q: What are the key differences between Cal Test Electronics CT3389 and Winchester 1329505?

A: Both parts maintain identical conversion direction (N Jack to SMA Jack) and core electrical specifications (50 Ohms, Female to Female). The CT3389 provides higher frequency capability (11 GHz vs 1 GHz) and ROHS3 compliance. The operating temperature range for CT3389 (0°C ~ 50°C) is narrower than 1329505 (-55°C ~ 100°C). Selection depends on frequency requirements and environmental operating conditions.

Q: Are all three parts interchangeable in the same application?

A: Mechanical and electrical interchangeability depends on circuit orientation and frequency requirements. Winchester 1329505 and Cal Test Electronics CT3389 share identical conversion direction (N to SMA). Pomona Electronics 4299 has reversed conversion direction (SMA to N). All three maintain 50 Ohm impedance and identical connector types. Frequency performance varies: 1329505 (1 GHz), CT3389 (11 GHz), 4299 (12.4 GHz). Selection must account for application frequency range and environmental temperature specifications.

Q: What compliance certifications apply to each part?

A: Winchester 1329505 is RoHS Compliant with MSL 1 (Unlimited). Pomona Electronics 4299 is REACH Affected, requiring verification against specific regulatory frameworks. Cal Test Electronics CT3389 is ROHS3 Compliant and REACH Unaffected. All three parts carry EAR99 ECCN classification and 8536.69.4010 HTSUS code. Regulatory requirements for the specific application determine compliance suitability.

Q: How do material and finish differences affect performance?

A: Winchester 1329505 uses Brass body with Nickel finish and Brass center contact. Pomona Electronics 4299 uses Beryllium Copper body with Gold finish and Beryllium Copper center contact, providing enhanced durability and signal integrity. Cal Test Electronics CT3389 uses Brass body with Nickel finish but Beryllium Copper center contact material. Material composition affects mechanical durability and electrical performance characteristics. Gold plating provides superior corrosion resistance compared to Nickel finish.

Q: What packaging options are available?

A: Winchester 1329505 packaging is not specified in available documentation. Pomona Electronics 4299 is supplied in Bulk packaging. Cal Test Electronics CT3389 is supplied in Bulk packaging. Bulk packaging indicates standard industrial quantities without specialized protective enclosure. Specific packaging requirements should be confirmed with supplier documentation.
