Parameter Comparison

Engineering Selection Recommendations

901-9221-2A (Amphenol RF) is the primary direct substitute for the 1051157-1. This part maintains identical connector geometry, termination method, and impedance specification. The 901-9221-2A operates at higher maximum frequency (18 GHz versus 12 GHz) and extended temperature range (-65°C to 165°C versus -65°C to 125°C), providing enhanced performance margin. The part is active in production status with ROHS3 compliance and REACH affected designation. Cable group compatibility extends to both .085" and .086" semi-rigid RG-405 configurations.

SF2915-6001 (Amphenol SV Microwave) serves as an alternative direct substitute with identical core specifications. This part operates at 12.4 GHz maximum frequency, meeting the minimum 12 GHz requirement of the original part. The SF2915-6001 is active in production with ROHS3 compliance. Operating temperature range is not specified in available documentation. This part carries REACH unaffected status, which may be advantageous in certain regulatory environments. Cable group compatibility is specified for RG-405 .085" flexible configuration.

142-0694-101 (Cinch Connectivity Solutions Johnson) functions as a direct substitute with identical connector type and termination specifications. This part supports 18 GHz maximum frequency and extended operating temperature range (-65°C to 165°C). The voltage rating of 500 V exceeds the original 335 V specification. Cable group compatibility is specified for RG-402 .141" semi-rigid, which differs from the original RG-405 .085" specification. This part is active in production with ROHS3 compliance and REACH affected designation.

All three substitute parts maintain the 500 mating cycle specification and PTFE dielectric material consistent with the original component. Selection should be based on specific cable group requirements, regulatory compliance needs, and performance margin requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 901-9221-2A directly replace the 1051157-1 in existing designs?

A: Yes. The 901-9221-2A maintains identical SMA plug male pin configuration, 50 ohm impedance, right-angle free hanging solder termination, and threaded fastening. Both parts support RG-405 .085" semi-rigid cable. The 901-9221-2A provides enhanced frequency capability (18 GHz versus 12 GHz) and extended operating temperature range (-65°C to 165°C versus -65°C to 125°C), making it functionally compatible for direct substitution.

Q: What is the primary difference between SF2915-6001 and 901-9221-2A?

A: Both parts are direct SMA plug male pin right-angle solder substitutes. The SF2915-6001 specifies RG-405 .085" flexible cable compatibility, while the 901-9221-2A supports both .085" and .086" semi-rigid configurations. The SF2915-6001 carries REACH unaffected status, whereas the 901-9221-2A is REACH affected. Operating temperature range for SF2915-6001 is not specified in available documentation.

Q: Why is 142-0694-101 listed as a substitute if it uses RG-402 cable instead of RG-405?

A: The 142-0694-101 maintains all critical electrical and mechanical connector specifications: SMA plug male pin, 50 ohm impedance, right-angle free hanging solder termination, and threaded fastening. The cable group difference (RG-402 .141" versus RG-405 .085") represents a mechanical variation that requires evaluation against specific application cable routing and space constraints. The connector interface itself remains fully compatible.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 1051157-1 is RoHS Compliant. All three substitute parts (901-9221-2A, SF2915-6001, and 142-0694-101) are ROHS3 Compliant, representing the current regulatory standard. ROHS3 compliance encompasses RoHS 2 requirements with additional restrictions on phthalates.

Q: What is the significance of REACH affected versus REACH unaffected status?

A: REACH affected status indicates the part contains substances of very high concern (SVHC) listed under the REACH regulation and requires specific documentation and compliance procedures. REACH unaffected status (SF2915-6001) indicates the part does not contain listed SVHC substances. Selection between REACH affected and unaffected parts depends on end-use application regulatory requirements and supply chain documentation capabilities.

Q: Do all substitute parts support the same mating cycle specification?

A: Yes. The original 1051157-1 and all three substitute parts (901-9221-2A, SF2915-6001, and 142-0694-101) specify 500 mating cycles, indicating equivalent mechanical durability and connector life expectancy.

Q: What is the moisture sensitivity level (MSL) and why does it matter?

A: Moisture Sensitivity Level indicates the component's susceptibility to moisture absorption during storage and handling. The 1051157-1, 901-9221-2A, and 142-0694-101 all specify MSL 1 (Unlimited), meaning no special moisture control measures are required during storage or handling. The SF2915-6001 specifies MSL Not Applicable, indicating the component does not require moisture sensitivity classification.

Q: Can the 1051157-1 be used interchangeably with the Winchester Interconnect 917A704A listed in the substitute data?

A: No. The 917A704A is an SMA Jack (female socket) panel mount connector, fundamentally different from the 1051157-1 plug (male pin) free hanging configuration. These represent complementary mating connector types, not substitutes. The 917A704A is included in the reference data as a related component but is not a functional equivalent.
